Application April 15, 1938, No. 202,251 4- Claims. @L15-135) The invention relates to brushes and more particularly to that type of brush sometimes called a fountain brush, wherein the brush is associated with a container for feeding a paste or liquid to the brush for spreading by the brush. The present application forms a continuation in part of my application, Serial No. 165,855, filed September 27, 1937, for Shaving brush.

An object of the present invention is to provide a brush of the character described which is particularly arranged for use as a shaving brush and for association with a collapsible tube of shaving cream, and wherein the means of connection between the brush is so arranged as to provide the attachment of substantially all of the various sizes of such tubes at present in common use.

Another object of the invention is to provide a fountain brush of the character described wherein the brush proper is connected to the discharge neck of a collapsible tube and wherein such neck is sealed both at its inner and outer annular surfaces to the brush support and the means provided thereby for conveying shaving cream to the brush.

A further object of the invention is to provide a shaving brush of the character above which is designed and constructed to catch soap and water drippings from the brush and prevent the running of such drippings onto the handle of the brush.

Still another object of the invention is to provide a fountain brush of the character described wherein a continuous sealed and unobstructed v passage ls provided for the shaving cream from the interior of the tube to the interior of the brush base.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.

Referring .to said drawing:

Figure 2 is a perspective view oi the brush as the same appears when ready for use.

Figure 3 is a perspective view showing the brush as the same appears when covered and set aside after use.

Figure 5 is a slightly enlarged longitudinal sectional view showing the mode of attachment of.

' thebrush support to a collapsible tube.

The brush of the present invention as depicted in the accompanying drawing, consists briefly of a brush proper i and a base support 8 therefor which is in turn provided with means 9 for connection to a collapsible tube ii of material to be applied by the brush. In the present form of the invention the means 9 consists in part of an end portion i2 ot a conduit I3 which extends from an end il of the base part and is arranged for insertion directly into the open neck end i8 of the tube Il. The conduit extends longitudinally through the support 8 and directly into the base il of the brush 'l and the inner end I8 of the conduit is preferably extended somewhat beyond the adjacent end wall i9 of the support, so as to discharge the contents of the tube in a portion of the brush base not rigidly secured in the support.` In this manner, the conduit .i3 extends at the end i2 directly into the interior of the tube Ii and forms a smooth, continuous andsealed passage for the tube contents to the opposite end i8 of the conduit directly in the lower body portion of the brush l. The material when discharged from the endi8 of the tube will work its way through the brush bristles for applying at the outer surfaces 2i of the brush.

As an important feature of the present invention, the end i2 of the conduit is preferably tapered for ease of insertion into the neck of the collapsible tube and for tightly securing the conduit end within the tube neck. The taper also provides for the fitting of various size tube necks on the conduit end so that substantially any size tube in common use may be used. Preferably, in order to facilitate attachment of the tube to the conduit end and to provide a better seal between such end and the conduit neck, the end I2 is threaded so as to cause a penetration of the thread portions of the end into the relatively soft j metal from which the neck of the collapsible tube is commonly constructed.

In addition to the connection of the tube neck to the conduit end I2, I prefer to also connect the tube neck directly to the body portion of the support 8, so that a more rigid connection with the tube is provided and a better seal'with'the tube neck is effected.. To accomplish this latter con- In attaching the neck of a collapsible tube to the connection means of the present brush, the neck of the tube may engage at various longitudinal positions on the conduit end I2, depending upon theinternal diameter yof the neck. Where this neck is of relatively small internal diameter, the saine will be engaged by the tapered end I2 t0- wards the extremity of such end and upon rotation relative to the support. will be threaded'onto the conduit end I2 and expanded thereby into threaded connection with the wall 23 of the body to tightly secure the tube to the support l. Where the tube neck has a larger internal diameter, the same will initially engage the tapered conduit end I2 at a more inwardly position and will consequently extend further into the bore 22 before the same is wedged between the tapered periphery of the conduit and the inner surface 22 of the bore. In this manner substantially all types and sizes of collapsible tubes having a discharge neck of the character described may be used in conjunction with the present brush, and in all of such cases, regardless of the size of the tube, a positive and fixed attachment and seal of the tube and support is provided.

The support 8 is preferably constructed of a plurality of sections 21 and 28 so as to facilitate the manufacture of the brush. As here shown, the section 21 is of substantially tubular form and is arranged to surround the base ends of the brush bristles and to provide a chamber 29 in which such bristles may be cemented. Prefera-` bly, the member is provided with an internal shoulder II adjacent the end I9 of the support.

so as to confine the bristles and cement base 1.

therefor against removal fromthe chamber 29. The section 28 is preferably of cylindrical form and is provided with a reduced inner end portion I2 which is adapted for insertion into the sleeve 21 to abut the base of the brush bristles and define an end wall 22 for the chamber 29. Preferably, the conduit I8 which extends longitudinally through these sections, is provided with a shoulder 24 which is adapted to seat in a recess' 2l formed in the end wall I2 of the section I and preferably, the shoulder yll and the recess 2l are of non-circular form so as to prevent relative rotation of the conduit and brush support. In this manner, it will be seen that the cement used for securing the brush bristles in the body of the supporting member also operates to rigidly secure the several parts of the supporting member together. Preferably, the sections 21 and 23 are provided with curved annular surfaces 21 and 28 which are complementary to each other in forming a smooth, continuous annular concavity around the base I for improving the engement of such base in the hand of the user.

As a further important feature of the present invention the end surface I8 surrounding the base portion I1 of the brush is preferably concave so as to provide a dishfshaped end of the support for catching soap and water drippings and the like from the brush and preventing such drippings from running onto handle portion of the brush. Preferably, I also provide a cover I for the brush when not in use and which may be readily attached to or removed from the brush as desired. As here shown, the cover I! is in the form of an inverted cup having aportion 4I of the side wall adjacent the open end thereof tapered and arranged toslidably nt a tapered annular wail portion 42 of the section 21 adjacent the surface I9. In this manner the cup may be slipped onto the section 21 or removed therefrom without the `use of threads or other more cumbersome attaching means. Preferably, the outer end 42' of the cup is substantially flat, so as to enable the brush assembly to be inverted and supported on such surface. as illustrated in Figure 3, when the brush is enclosed by the cup and set aside aiteruse.
